--ing Can Gaps and Collars Together, of which 'Be it known that I,-MIL TQN B,. CAPPS, a citi-. zen of the United States, residingat Philadelr phia, in the county of Philadelphia and State of Pennsylvania, haveinvented a certain new and useful Improvement inMachinesforBrazthefollowi'ng is a specification a 7 My invention relates to 'a new. and useful ingfhe necessary heat to the collars and caps to H raze them-together,

Withthe'se ends in view this inventioncom sists inthe details of construction and combination of elementshereinafter set forth and then specifically designated by the claims.

I In order that those'skilled in the art to t j which'this invention appertains mayunder- .,stand how tomake and use the same, the construetio'n and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in

which- Figure lis a plan viewof the turntable of j the machine, showing the gas-heaters extend: 3

5o ln carrying out my invention as here em? machine nowin use for brazing the collars and caps together, which consistsof a hubA, mounted .upon a. central stationary spindle B,,;which hub carries aturn-table 0-, adapted to be'revolved by-Ls'uitable mechanism; and

, bodied I utilize for the most part theforrn of this turn-table'is-provided at itsouter 'circumfere'nce with depending brackets D, in. 5

which are fitted the plungers slide vertical'l ,and these plung'ershave pivoted'thereto t 'e'levers F, as indicated at G, said levers being fulcrumed at H and-having suspended therefrom the weights 1.. This arrangement' provides' for the raising and lowering of said plungerslby the actuation of the let erswhich is accomplished automatically by the stationary-cam J, securedto the base K, suitable antifriction-rolls L being ,journaled upon the levers, so as to facilitate 1 the travel of'the levers upon thecam. The

E, adapted ,to 6o inner ends of the levers are held against lateral displacement the vertical guide-strips M. The upper ends of the 'plungers terminate in -heads N for the'receptio'n of the col-' I lars, by means of which said collars and the caps. laid thereon may belcarriedj with the plungers in their rotation with: the turn-table.

As thus far described the machine is the same as now used for brazing the caps and collars together; but-heretofore it has been' necessary to place a brazing-iron by hand upon each cap and: leave it in. contact with the cap until'the brazing was eifected and then removesaid iron by hand. "This of necessity made theoperation of the machine comparatively slow, while at theisame timerequiring three operators to perform; this work; but by my improvement which will next be explained, this difiicultyiis entirely obviated and the machine made automatic.

I'form in the outer portion of the turn-ta- Me a series of holes'o, each of which correspends imposition with one of the plungers, and beneath each of these holesis secured a brazing-iron P.- Aseries of-gas-heaters Q are locatedimmediately above the=turn-table, the

lower faces thereof hearing against the upper 7 surface ofsaid table, and theseheaters are provided with the perforations-R, from which the air-mixed gas issnes an'd when lighted each'of the jets of gas forms a flame which when tected against the brazing-irons heats them to a snfiicient degree to bring about the brazing, as will be hereinafter set forth, The heaters extend to about'one-third ofthe circumference ofthetur'n-table, each being seing thebrazing, and. the heater Q, which is 10- sated at the beginning of the series of heaters,

for the pilot-flame T, which remains lighted cured to those next adjacent by suitable bolts passed-through the ears S, so that. when the table revolves each-of the holes will successively pass beneath all of the heaters, therebysnbjecting thebrazing-irons to the gas-flames issuing from said heaters, thus insuring the proper temperature of said irons for produc':

has its outer'edge beveled, so as to provide during the operations of the machine, so that when the rotations of the turn-table carry hole 0 beneath the heater Q the jets: of gas issuing therefrom will be ignited from the pilot-flame, ,a-nd'as the hole passes from besively off by the upper surface of the turntable, which acts as a slide-valve therefor, while at the same time the jets issuing from the perforationsof the next adjacent heater will be lighted by thelast of the jets of the heater Q. By the continued; rotation of the table this process will be repeated from one heater to another througlout the entire series, thus gradually raising the temperature of the braz: ing-iron until completing the brazing of the capto the collar.. In feeding themachine a single operator places a collar in an inverted position upon each of the heads N and places a cap npon'the top of each collar, the cap being countersunk, as indicated at U, so as to be guidedin place upon the collar, and this feeding is done while the table is revolving v and upon the side at'which the plungers are sufficient portion of the revolution of the tadrawn downwardto'their lowest limit. After the collars and caps have been fed to the machine the. revolving of the turn-table will carry the levers. traveling upon the cam J to that portion of the cam which permits the inner end of said levers to'move downward, which is effected by the weights I. This downward movement of the inner portion of "the levers forces the plungers outward, as is obvious, and thus carries the caps against thebrazing-irons, where they are held during a ble to effect their welding, as before set forth, when they are released by. the levers again riding up'upon the cam' J, and they may then be remo'vcd by the operator which fed them found necessary. v It is to be noted that the caps and collars are 'to the machine or by another operator, if-

. made of tin, which serves to unite the two when .the proper heat and pressure are brought to-bear thereon, as is well understood. I a The suitable admixture. of gas and airis therewith, as specified.

"eanveyed the heaters by the pipes V, which .fmay be rovidedwith valves for the regula+ 7 By the arrangement of -the heaters as here showna greaterforrless number may be used in the series by removi ii-gthe end heaters or adding others theretb,fi tbeing only necessary to couple or-'uncouple.theijoints formed by i. In useinyi'mprovementgsaves at least-two operators in operating the machine, while at the same time increasing its capacity by permitting it being run-at a higher rateof speed, and the work produced by the machine is-improved in quality. Y

Of course Ldo not-wish to l-imit myself to theexact details of construction herefshown, f as these may be varied within ,certain limits without departing from the spiritoffmy in- ,vention. 4 1
